[3] Used by thousands of immigrants to the west from 1843-1851, the pass is a National Historic Landmark.
[4] The pass lies a few miles west southwest of Scottsbluff, Nebraska in broken country south of the North Platte River and the Wildcat Hills.
Scotts Bluff blocked wagon travel along the south bank of the North Platte River, forcing early travelers to swing south and go through Robidoux Pass, a natural gateway in the great bluffs.
Robidoux Pass is located south of Scotts Bluff National Monument, 4.5 miles (7.2 km) south and 8 miles (13 km) west of Gering, Nebraska off Nebraska Highway 71 on Robidoux Road.
